When you want to remove all waypoints, do '''NOT''' iterate over ''waypoints _group'' while trying to delete them (an array is by reference!). Instead use an approach like this:
<code>
[[while]] {([[count]] ([[waypoints]] _group)) > 0} [[do]]

Description

Description:
Removes the specified waypoint.
ⓘ
  • When a waypoint is deleted, all other group waypoints are immediately re-indexed. See Example 2 for a deletion of all group's waypoints.
  • Deleting a group's current waypoint will not stop the group on its tracks.
Groups:
Uncategorised

Syntax

Syntax:
deleteWaypoint [group, index]
Parameters:
[group, index]: Array
group: Group
index: Number
Return Value:
Nothing

Examples

Example 1:
deleteWaypoint [_grp, 2];
Example 2:
Because waypoints get immediately re-indexed when one gets deleted, delete them from last to first: private _group = group _unit; for "_i" from count waypoints _group - 1 to 0 step -1 do { deleteWaypoint [_group, _i]; };

Another (more foolproof) method to avoid the problem of non-deleteable waypoints is to introduce another group (createGroup) and join all units of the present group. A new group will start without any preset waypoints so you can start setting new WPs all over again. Old group is "_combatGroup", new group is "_combatGroup2" _combatGroup2 = createGroup east; { [_x] joinSilent _combatGroup2 } forEach (units _combatGroup); _combatGroup2 addWaypoint [getPos player, 25];

Mr H.
To have the unit stop on the spot you need to set its current waypoint where it is and add a little delay, as stated above by Saintolaf so: group _unit spawn { [_this, (currentWaypoint _this)] setWaypointPosition [getPosASL ((units _this) select 0), -1]; sleep 0.1; for "_i" from count waypoints _this - 1 to 0 step -1 do { deleteWaypoint [_this, _i]; }; }; Will stop the group where it is and delete its waypoints.
